Why did the pilots pass out and not the passengers? How did the passengers get access to the cockpit?
I wonder if one person was able to TM his cousin, the pilots never noticed any signals(waving, etc.) from other passengers? I guess the pilots visually scanned the windows. Or maybe the 'texter' guy noticed the F-16s and assumed pilots were not responding after a while. There was a report of 2 persons trying to take control of the plane, why wouldn't one of them make a signal or some sort of alert. Im sure they would have noticed the fighter planes.
